Yes I have the xlibmesa-gl, libglu1-mesa, libglu1-mesa-dev, etc, libraries.

Hi!
There is a function ?dir which returns you the content of the dir_ectory.
If this is more then there is a function ?grep which allows you to
extract relevant items.
If you need to postprocess the names you have a function ?paste for example.
And finally you have an S language construct

Hello:
Im hoping the list can shed light on two items. I am

1) The model works fine using varIdent(~1|factor) and

varComb(varIdent(~1|factor),varFixed(~covariate)), but
not when varFixed(~covariate) is used

Hi
I use gnls to fit non linear models of the form y = alpha * x**beta
(alpha and beta being linear functions of a 2nd regressor z i.e.
alpha=a1+a2*z and beta=b1+b2*z) with variance function
varPower(fitted(.)) which sounds correct for the data set I use.
My purpose is to use the fitted models

Tried to do that with par(bg) but only changed the color of the trellis

What's the right command to do
What you should realize is that xYplot() uses lattice, and that color theme
is the default for lattice. trellis.device() has the `theme' argument that
you can use to change it. The help page explains how you can change the
default:
theme: list of components that change the settings of the
